Registering an event (no offset)
Registering an event without reference offset is the most common type of event registration. This workflow requires that you register an event using either an internal event table or external event table.
- Start ArcMap and open the Catalog window or start ArcCatalog.
- In the Catalog tree, connect to the geodatabase that contains the ALRS and LRS Network for which you want to add event layers.
- Expand the ALRS that contains the LRS Network for which you want to add event layers.
- Right-click the LRS Network and click New > LRS Event.
The ALRS Event Setup wizard appears.
- Click Next.
- Select Event (no offset).
- Click Next.
- Type a name for your event layer in the Event Name text box.
- Verify that the parent network is set to the correct network.
- Click the browse button next to the Event Table text box.
The Browse Data dialog box appears.Note:
External events can use OLE DB connections. For more information about setting up OLE DB connections in your database, see Connecting to an external event source.Note:
When adding local events to an SDE geodatabase, the event table must be registered as versioned.
- Browse to the business table for which you want to create an event layer and click Select.
If the table you browse to is in the same geodatabase as your LRS Network, you will create a local event. If the table you browse to is outside of the geodatabase, you will create an external event. You must use caution to ensure you are pointing to the correct location when you browse to your business table. For more information about local and external events, see Advanced linear referencing—staging tables.
The Create New LRS Event dialog box is populated with information from the event table.
- Verify and update the rest of the information on the Create New LRS Event dialog box as needed.
- Set the Event ID Field.
- Set the Route ID Field.
- Set the From Date Field.
- Set the To Date Field.
- Set the Time zone.
- Set the event type by choosing either the Point event or the Line event button.
By default, the Event ID Field is used as the primary key when the From Date Field and To Date Field are not defined.
If the From Date Field and To Date Field are defined, the primary key uses a combination of the Event ID Field, From Date Field, and To Date Field.
If the external table supports the Roads and Highways temporality model at the time the event is created, you must specify the From Date Field and To Date Field fields.
If the From Date Field and To Date Field fields are not provided, Roads and Highways assumes that the external table does not support temporality and expects only one entry per event. In this scenario, the Event ID column is treated as unique.
If the From Date Field and To Date Field fields are specified for the external event table, then Roads and Highways uses the appropriate record for the given temporal view date.Note:
Ensure the values in the FromDate and ToDate columns are not conflicting.
Regardless of whether external event tables support temporality, the staging table will always contain FromDate and ToDate columns.
- Set the from and to measure fields.
- Click Next to set event behavior.
For more information about setting event behavior, see Advanced linear referencing—Rule-based location management.
- Click Next to set perpendicular offset.
For more information about perpendicular offsets, see Setting perpendicular offsets for events.
- Click Finish.
